Alternate Views: You can use AlternateViews to specify copies of an e-mail message in different formats. For example, if you send a message in HTML, you might also want to provide a plain text version in case some of the recipients use e-mail readers that cannot display HTML content. Supported in .NET 2.0 and higher.

Validation Timeout: You can use the ValidationTimeout property to specify the validation timeout period in milliseconds. It returns the highest validation level, and sets the TimeoutExpired property to True if it times out before completing the validation process.

Events: You can use the following three events to customize the mail merge process per your design needs:

OnBeforeMerge: Customize the raw message fields before merging them with actual data

OnBeforeSend: Make modifications and address validations just before sending a message
